JAMES SITT, OF INDIANAPOLIS, INDIANA.

GRAIN-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 224,801, dated February 24, 1880.

` Application led September 15, 1879.

To all whom it may concern:

Be 4it known that l", JAMEsB. SUITT, of the city of Indianapolis, county vof Marion, and State of Indiana, have invented certain new and useful Improvements in Grain-Separators, of which the following is a specification, reference being had to the accompanying drawings, which are 'made part hereof, and on which similarletters of reference indicate similar parts.

Figure l is a plan view of the interior of a thrashing-machine embodying my invention. Fig. 2` is a longitudinal vertical section thereof on the dotted line as fr, Fig. l. Fig. 3 is a transverse vertical section on the dottedline e a, Figxl. Fig. 4 is a plan view of one set of `the lifting-lingers and their shaft detached machine from the machine.

'In said drawings, the portions marked A represent the frame-work and sides of the 5 B, the thrasher cylinder or beater; C, the floor-sections, composed of the inclines C C', and, when lifting-lingers are used, having the projections cc, to operate said lingers,

and usually, also, the recesses c c', to receive the iinger-shafts; D, the crank-shaft, which drives the iioor; E, the rods which bear the liftinglingers; F, thelifting-fingers, having' pipe-like bearings F', G, a graincarrier tloor; H, a connecting-rod, connecting said door to the crank-shaft D, and I the bar or rod sup porting the front endof the Hoor-sections.

The general object of inventions of this class is to provide means to lthorou ghl y agi tate the straw in its passage through thc machine,

`and thus dislodge all grain therein, so that no waste shall occur.

My improvement mainly consists in mounting the lifting-ingers separately upon tubular bases, which, in turn, are mounted upon rods running through the machine, and ordinarily rigidly attached to the sides thereof. Each finger is thus independent of the others, and rises and falls in unison with the section of door over which it is located. As the tloorsections move alternately the lingers also have an alternate motion, which is much more effective in shaking up and separating the straw than the uniform movement which fingers have `which are rigidly attached to their shaft.

the location of the iingereshaft in relation to the'lioor. Ordinarily such shafts have been run across the top of the iioor or below the floor, with the fingers bent an d passing through slots cut through the sections. In one case the stationary shaft has seriously impeded the passage of the straw, while in the other the large slots necessary to allow the proper working of the fingers have been undesirable. I have devised a system of recesses, c', in the form shown, to receive the fingershafts E, whereby they are entirely out of the way of the passing straw, and the cutting of holes through the floor is rendered unnecessary.

The fingers in my `invention are actuated by upwardly -projecting pieces c upon the iioorsections immediately beneath said lingers, andY lift them, as the licor-sections make their forward movement, and allow them to tall as they move backward.

The construction and arrangement of parts herein shown and described is exceedingly eflicient in attaining the object hereinbefore stated.

Having thus fully described my said invention, what I claim as new, and desireto secure by Letters Patent, is

1. In combination with a straw-carrier oor composed of alternately-reciprocatin g sections, lifting ngers independently mounted and each actuated independently of the others, substantially as herein set forth.

2. In combination with the alternately-reciprocatin g sections of the straw-carrier iioor of a thrashing-machine, lifting-fingers operated independently of each other by suitable projections attached tothe sections upon which said fingers rest, substantially as shown and specified.

In witness whereof I have hereunto set my hand and seal at Indianapolis, Indiana, this llth day of September, A. D. 1879."
